Step 7: Strain out the sodium alginate and you have your edible polymer.

Step 8: You can even use the polymer as an ice cream topping.

Working Principle of Edible Polymer :

Edible Polymer, a form of polymer which one can actually be used for edible purposes. It is prepared by using calcium acetate and sodium alginate solutions prepared in water. Here, calcium acetate acts as an activator agent for colored sodium alginate balls. Edible polymer can be used as an ice-cream and cup-cake topping and can also be directly consumed. It is different from worm slime as calcium acetate is used to make this polymer which makes it edible.
